Methods and Arrangements to Determine Station Assignments to Restricted Access Windows in Wireless Networks

1. An apparatus comprising: circuitry to cause a wireless communication device to form restricted access window (RAW) group fields of a RAW parameter set information element (RPS element), the fields comprising: a Page index, a RAW Start Association Identifier (AID), and a RAW End AID, wherein: the Page index, the RAW Start AID, and the RAW End AID to collectively identify a group of one or more stations permitted to access a medium during a RAW, the Page index is to identify a page index for the group of one or more stations, the RAW Start AID comprises a portion of an AID of a first station in the group of one or more stations and the first station to have a corresponding RAW, the RAW Start AID comprising 11 least significant bits (LSB) of the AID of the first station, and the RAW End AID comprises a portion of an AID of a second station in the group of one or more stations and the second station to have a corresponding RAW, the RAW End AID comprising 11 LSB of the AID of the second station; and circuitry to cause the wireless communication device to transmit a wireless transmission comprising the RPS element.

2. The apparatus of claim 1 , wherein: the Page index comprises 2 bits, the 2 bits comprising two most significant bits (MSB) of the AID of the first and second stations.

3. The apparatus of claim 1 configured to cause the wireless communication device to: transmit the RPS element as part of a beacon frame.

4. The apparatus of claim 1 configured to cause the wireless communication device to: transmit a traffic indication mapping (TIM) information element (IE) in a same frame as that of the RPS element, the TIM IE comprising a TIM bitmap, each bit of the bitmap to indicate whether a station has buffered data at an access point.

5. The apparatus of claim 1 , wherein the RPS element is to identify RAW start time and RAW duration.

6. The apparatus of claim 1 comprising: physical layer circuitry; a radio communicatively coupled to the physical layer circuitry; at least one antenna communicatively coupled to the radio; at least one processor communicatively coupled to the radio; and at least one memory communicatively coupled to the at least one processor.

7. The apparatus of claim 1 comprising a Media Access Control (MAC) sublayer processor.

8. The apparatus of claim 1 , wherein the first station and the second station are a same station.

9. The apparatus of claim 1 comprising a memory and a processor.

10. At least one non-transitory computer-readable medium, comprising instructions stored thereon, which, when executed by one or more processors, cause a wireless communication device to: form restricted access window (RAW) group fields of a RAW parameter set information element (RPS element), the fields comprising: a Page index, a RAW Start Association Identifier (AID), and a RAW End AID, wherein: the Page index, the RAW Start AID, and the RAW End AID to collectively identify a group of one or more stations permitted to access a medium during a RAW, the Page index is to identify a page index for the group of one or more stations, the RAW Start AID comprises a portion of an AID of a first station in the group of one or more stations and the first station to have a corresponding RAW, the RAW Start AID comprising 11 least significant bits (LSB) of the AID of the first station, and the RAW End AID comprises a portion of an AID of a second station in the group of one or more stations and the second station to have a corresponding RAW, the RAW End AID comprising 11 LSB of the AID of the second station; and transmit a wireless transmission comprising the RPS element.

11. The at least one non-transitory computer-readable medium of claim 10 , wherein: the Page index comprises 2 bits, the 2 bits comprising two most significant bits (MSB) of the AID of the first and second stations.

12. The at least one non-transitory computer-readable medium of claim 10 , wherein the instructions, when executed by the one or more processors, cause the wireless communication device to: transmit the RPS element as part of a beacon frame.

13. The at least one non-transitory computer-readable medium of claim 10 , wherein the instructions, when executed by the one or more processors, cause the wireless communication device to: transmit a traffic indication mapping (TIM) information element (IE) in a same frame as that of the RPS element, the TIM IE comprising a TIM bitmap, each bit of the bitmap to indicate whether a station has buffered data at an access point.

14. The at least one non-transitory computer-readable medium of claim 10 , wherein the first station and the second station are a same station.

15. A method comprising: forming restricted access window (RAW) group fields of a RAW parameter set information element (RPS element), the fields comprising: a Page index, a RAW Start Association Identifier (AID), and a RAW End AID, wherein: the Page index, the RAW Start AID, and the RAW End AID to collectively identify a group of one or more stations permitted to access a medium during a RAW, the Page index is to identify a page index for the group of one or more stations, the RAW Start AID comprises a portion of an AID of a first station in the group of one or more stations and the first station to have a corresponding RAW, the RAW Start AID comprising 11 least significant bits (LSB) of the AID of the first station, and the RAW End AID comprises a portion of an AID of a second station in the group of one or more stations and the second station to have a corresponding RAW, the RAW End AID comprising 11 LSB of the AID of the second station; and triggering wireless transmission of the RPS element.

16. The method of claim 15 , wherein: the Page index comprises 2 bits, the 2 bits comprising two most significant bits (MSB) of the AID of the first and second stations.

17. The method of claim 15 comprising: transmitting the RPS element as part of a beacon frame.

18. The method of claim 15 comprising: transmitting a traffic indication mapping (TIM) information element (IE) in a same frame as that of the RPS element, the TIM IE comprising a TIM bitmap, each bit of the bitmap to indicate whether a station has buffered data at an access point.

19. The method of claim 15 , wherein the first station and the second station are a same station.
